Prolin is an Internet worm, uses Microsoft Outlook to email itself. The worm is 36,834 bytes long {37KB} and written in Visual Basic 6. It needs "MSVBVM60.dll" to spread otherwise it will show DLL missing error. The e-mail attachment name will be "Creative.exe". While opening the email attachment, the Prolin worm will copy "Creative.exe" to root folder of C drive and Windows startup folder C:/WINDOWS/Start Menu/Programs/Startup/Creative.exe. So the creative.exe file is loaded automatically whenever Windows starts. I-Worm/Prolin also opens the Microsoft Outlook Address book and sends e-mail to all the email Ids stored. The message subject will be "A great Shockwave flash movie", the message body will be "Checkout this new flash movie that i downloaded just now... It's Great. Bye" and the attachment name will be "Creative.exe". It will show a similar icon to the shockwave movie. After that it sends a notification message to the virus author with subject "Job complete". It sends this message to a yahoo id [email protected] with the message body "Got yet another idiot".
